Bagging effect upon either quality of the fruits and incidence of the fruit borer in atemoya and sweetsop

This study was conducted to evaluate the effect from using different involucres for fruits of the atemoya and sweetsop upon either physiochemical quality of the fruits and incidence of the fruit borer Cerconota anonella. The experiments were set up in two commercial orchards: one with atemoya at Matias Cardoso county and the other one with sweetsop at Verdelândia on northern Minas Gerais state. The treatments for atemoya consisted of: 1) Control (without bagging); 2) Milky plastic bag; 3) White, bottomless, tissue-non-tissue (TNT) bag; and (4) With bottom TNT bag. For the sweetsop, only treatment 2 was modified to brown paper bag. The following evaluation were performed: the number of days from pollination to harvest, number of days from harvest to ripening, occurrence of injuries and borers, and the physiochemical characteristics of the fruits. The no-bagged sweetsop fruits showed higher number of days between the harvest and ripening and higher firmness. The use of the milky plastic controlled the borer in atemoya fruits. The following physiochemical characteristics were not affected by the use of those involucres: weight, length, fruit diameters, and the content of the total soluble solids in the pulp.
